BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to hospital equipment. More specifically, the present invention is drawn to a footboard extension rail for the footboard of a conventional hospital bed.

2. Description of the Related Art

In many instances, patients in institutions such as hospitals, nursing homes and the like must restrained from exiting, their beds without assistance and without extreme physical restraints, such as tie-downs. Such patients are placed on what is called “fall prevention status”. Conventionally, extension rails have been positioned along the sides of the bed and have been effective in preventing the patients from exiting via the sides. Since the head of the bed is usually disposed adjacent a wall, exiting the bed in this direction is also blocked. However, patients may consider climbing over the footboard as a viable exit, thereby risking serious injury and equipment damage. A durable barrier that can be efficiently attached to the footboard of a conventional hospital bed and that would deter exiting the bed in this direction would certainly be a welcome addition in the art. Thus, a footboard extension rail solving the aforementioned problems is desired.

SUMMARY OF THE INVENTION

The present invention is drawn to an extension rail for the footboards of conventional hospital beds. The extension rail employs a modified side rail. The modification includes stabilizer bars attached to a convoluted rail. The stabilizer bars fit around a lower portion of the footboard. A unique, spring-biased locking mechanism is employed to lock the rail in its extended position. A conventional clamping arrangement is utilized to attach the extension rail to the bed frame.

Accordingly, the invention presents an extension rail for a footboard that is easy to install and remove from the footboard of a bed. The invention provides for improved elements thereof in an arrangement for the purposes described that are inexpensive, dependable and fully effective in accomplishing their intended purposes.

These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Attention is first directed to FIG. 1 wherein the footboard extension rail system of the present invention is generally indicated at 10. As illustrated, the rail system is attached to the frame of the bed at the inside surface of a footboard 12. The footboard 12 has an outer, planar surface 14, a portion of the surface 14 being encompassed by a stabilizer bar apparatus. Rail system 10 functions to deter a patient P from exiting the bed at the foot thereof. Conventional side rails (not shown) would be positioned at the sides of the bed.

As best seen in FIG. 2, rail system 10 comprises horizontally spaced, vertical, tubular end members having respective upper ends 20 and 22 telescopically received in respective lower ends 20 a, 22 a. The space between the tubular members is traversed by plural, convoluted tubular cross-members 24, 26, 28. The cross-members 24, 26, 28 are attached to the upper ends 20 and 22. A stabilizer apparatus, comprising upper and lower bars 30, 32, is attached to the rail system. Each bar 30, 32 is provided with L-shaped ends 30 a, 32 a attached to the lower ends 20 a, 22 a of the respective tubular end members. Cross-members 24, 26, 28 and bars 30 and 32 are provided with telescoping sections for easy adjustment.

As best seen in FIG. 3, a spring-loaded clamping member 34 is telescopically installed on the lower ends of lower members 20 a and 22 a. Spring-loaded clamping member 34 functions to attach the rail system 10 to the bed frame.

The spring-biased mechanism for locking the telescoping upper ends 20 and 22 in raised positions is best illustrated in FIG. 4. An elongate rod 40 is disposed inside upper bar 30 and is movable therein. Rod 40 is attached at one end to a vertically oriented first locking pin member 42. The other end of rod 40 is attached to a vertically oriented second lock pin member 44. Lock pin members 42 and 44 are housed within lower tubular members 20 a and 22 a. Springs 46 are attached to lock pin members 42, 44 and function to bias lock pin members 42, 44 into locking engagement with respective lock members 42 a, 44 a. A knob 50 is attached to rod 40. The knob 50 is slidable to move rod 40 to disengage the lock pin members 42 and 44 when it is desired to lower the railing 10. Spring 52 is employed to bias knob 50 to a locked position.
